Installing Drupal

Hello. I get this error when I load drupal, wondering if anyone knows what the problem is? Thanks.

Fatal error: Table 'xs2.hud_variable' doesn't exist query: SELECT * FROM hud_variable in /home/x/s/xs/public_html/hud/includes/database.mysql.inc on line 90

I am using Drupal as a website for a college course. I would like to have three instances but have only one MySQL database. I have used database prefixes for my second installation. It appears to install but the side menu is not appearing so I don't have access to any of the configuration or content links. When I first installed I got some warning messages, but unfortunately did not write them down. Does anyone have good info to add to that already on the site about setting up multiple installations with one db?

Thanks

I download Drupal 4.4.0,and install it.
I want to show menubar.how do I do?

Whenever I try to create a new account I get the following error:

warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header missing in C:\www\drupal-4.3.2\modules\user.module on line 322.

Our host has a completely separate machine - db1.domain.com - to handle databases. How do I modify the CONF file so Drupal knows how to access it?

Nice smooth install.
Fixed the magic_quotes_gpc setting.
Database looks fine.
Created my first account.
Got the email delivery.
Tried to login... No error, but no login. I just end up back at the login page. I've checked my database, and the accounts are in there. I've tried resetting passwords - no help. I've tried to fail login - I get the failure message, so that's working.

My vague guess is that there is some kind of problem with the session, but I can't imagine what it is. I'm no php expert.

Any advice appreciated.
